6²+8²=c²
36+64=c²
c²=100
c=10
The correct answer is one solution
52 ft is less than 912.
There is 12 inches in a foot, so I did 52 x 12 = 624. 624 is less than 912.
20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
